IdentityServer Interaction Service

Duende.IdentityServer.Services.IIdentityServerInteractionService

The IIdentityServerInteractionService interface is intended to provide services to be used by the user interface to communicate with IdentityServer, mainly pertaining to user interaction. It is available from the dependency injection system and would normally be injected as a constructor parameter into your MVC controllers for the user interface of IdentityServer.

IIdentityServerInteractionService APIs

• GetAuthorizationContextAsync

  Returns the AuthorizationRequest based on the returnUrl passed to the login or consent pages.

• IsValidReturnUrl

  Indicates if the returnUrl is a valid URL for redirect after login or consent.

• GetErrorContextAsync

  Returns the ErrorMessage based on the errorId passed to the error page.

• GetLogoutContextAsync

  Returns the LogoutRequest based on the logoutId passed to the logout page.

• CreateLogoutContextAsync

  Used to create a logoutId if there is not one presently. This creates a cookie capturing all the current state needed for signout and the logoutId identifies that cookie. This is typically used when there is no current logoutId and the logout page must capture the current user’s state needed for sign-out prior to redirecting to an external identity provider for signout. The newly created logoutId would need to be roundtripped to the external identity provider at signout time, and then used on the signout callback page in the same way it would be on the normal logout page.

• GrantConsentAsync

  Accepts a ConsentResponse to inform IdentityServer of the user’s consent to a particular AuthorizationRequest.

• DenyAuthorizationAsync

  Accepts a AuthorizationError to inform IdentityServer of the error to return to the client for a particular AuthorizationRequest.

• GetAllUserGrantsAsync

  Returns a collection of Grant for the user. These represent a user’s consent or a clients access to a user’s resource.

• RevokeUserConsentAsync

  Revokes all of a user’s consents and grants for a client.

• RevokeTokensForCurrentSessionAsync

  Revokes all of a user’s consents and grants for clients the user has signed in to during their current session.
